Because of the recent increase of COVID-19 cases in my city and because of my obligations as a college student, I predict that I will not be able to ride my bike for more 3-5 weeks. I have just deep cleaned my bike, degreased, relubed it and everything, I'm going to park it in its stand and have a rainproof and dustproof bike cover over it that completely covers the bike and the stand. I plan to not do anything with it. When I finally get around to ride it, I'll definitely give it a deep clean again. Are there any negative effects to leaving my bike this way? Any components that need to be "aired out"?
Additional info: I've kept my bike in the garage with no cover for the four years I've owned it, with it getting splashed by whatever I do in there and dust accumulating being the only problems. Rain is not an issue. Climate in my region usually consists of heavy rains, and very hot days.
